EDWARD CROSSLEY, OF ERIE, PENNSYLVANIA.

NET-PULLING MACHINE.

Specification of Letters Patent.

Application filed September 4., 1912.

Patented Apr. 8,1913.

Serial No. 718,442.

To all whom it may concern Be it known that I, EDWARD CRossLEY, acitizen of the United States, residing at Erie, in the county of Erieand State of Pennsyl- Vania, have invented new and useful Improvementsin Net-Pulling Machines, of which the following is a specification.

This invention relates to net pulling Inachines and consists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out in the claims.

The object of the invention is to provide a simple and efficient meansfor pulling fish nets.

The invention is illustrated in the accompanying drawings as followsFigure 1 shows a plan view of the machine. Fig. 2 shows a frontelevation of the machine. Fig. 3 shows a plan view of one of thegripping jaws and frame. Fig. 4 a front elevation of the same parts.Fig. 5 a side elevation of the same parts. Fig. 6 a perspective view ofthe driving spring. Fig. 7 a plan view of the jaw actuating cam.

1 marks the base of the machine. This is secured to a deck as 2. Thedrive shaft 3 is journaled in the case 1 and extends ordinarily throughthe deck to a source of power (not shown). The reel 4 is ournaled in theshaft 3. The reel is formed with a web plate 5 of wrought iron. This webis secured between the parts of a hub 6 by rivets 7. The outer edge ofthe web is flanged and a wrought metal shell 8 secured to this flange.The clamp or grip frames 9 are secured to the shell 8 by rivets 10.These frames have the sloping gripping surfaces 11. Gripping jawsupporting arms 12 extend inwardly on the frame, and the gripping jaws13 are pivoted between the arms 12. The jaws are in the form of bellcranks, the jaw arm 14 extending forward to bring the jaw surface 15 toa position that will engage the surface 11 as the jaw swings. The jawsoperate between the upward extensions 16 of the frames 9. Projections 17extend circumferentially from the frame, one of the projections in eachframe being cut away at 18 so as to receive the end 19 of theproject-ion of the adjacent frame. The ends are secured together by therivets 20 so that the frames with their projections form a completeannulus. The frames also have the grooved project-ions 21 the bottoms ofwhich are continuations of the surfaces 11 so that when the jaws areopen the frames present a continuous groove to receive the net. It willbe noted that the gripping surface-11 and the bottom of this grooveslope downwardly. This assures the disengagement of the net when thejaws are opened.

The cam arms 22 of the jaws 13 extend downwardly through slots 23 in theweb 5 and terminate in rollers 24. The rollers operate against the cam25. The cam 25 extends fro-m the base 1. The cam has the cut awayportion 26. Springs 27 are secured to the arms 22 and extend inwardly toa floating ring 28.

The operation of the machine is as follows :The net as it is pulled isled into the groove under the jaws at a point just before where therollers pass off the cam 25. As the roller passes ofi the cam the spring27 pulls the jaw down to gripping position and the jaw is held in thisposition through the space 26. The space is suflicient to allow aboutfive jaws to close on the-net. When the roller passes the space 26 itcontacts the cam 25 and this forces the arm 22 out and the arm 14 up,thus releasing the net.

It will be noted that the floating ring shifts its position as the reelrotates by reason of the difference in the spring tensions of thesprings on the arms on the cam and springs attached to the arms in thespace 26. This permits of the use of comparatively short springs,inasmuch as the springs on the arms on the cam are relieved by theshifting of the ring and on the other hand the shifting of the ringpulls the springs on the arms in the space 26 inwardly so as to give thejaws proper pressure to hold the net. It will also be noted that theworking parts are so covered and protected as to prevent the netscatching in them.

It is preferable to yieldingly connect the reel with the drive shaft sothat if the reel catches, time may be had to stop the machine before thenet is damaged. For this reason, I provide the scroll spring 30. This isconnected with the collar 29 fixed on the shaft 3 and to a bracket 32 onthe web 5. The scroll spring permits of a close coupling of the parts sothe reel forms a housing preventing the catching of the net.

What I claim as new is 1. In a net pulling machine, the combination of areel having outwardly extending gripping surfaces thereon; jaws in theform of bell cranks pivoted on the reeland having one arm extendingoutwardly and engaging the gripping surface and the other arm extendingin an axial direction; and means acting on the axially directed arm foractuating the jaw.

2. In a net pulling machine, the combination of a reel having outwardlyextending gripping surfaces thereon; jaws in the form of bell crankspivoted 011 the reel and having one arm extending outwardly and engagingthe gripping surface and the other arm extending in an axial direction;a cam for forcing the axially directed arms outwardly to open the jaw;and springs secured to said axially directed arms to draw them inwardlyand to move the jaws to gripping position.

3. In a net pulling machine, the combination of a reel having outwardlyextending gripping surfaces thereon; jaws in the form of hell crankspivoted on the reel and having one arm extending outwardly and engagingthe gripping surface and the other arm extending in an axial direction;a cam for forcing the axially directed arms outwardly to open the jaw;springs secured to said axially directed arms to draw them inwardly andto move the jaws to gripping a ping surfaces and secured in series onthe shell to form a continuous band; jaws pivoted on the frames; andmeans for actuating the jaws as the reel is rotated.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
